Abstract: A source control management system comprises accessing a TPF platform via a web interface. The system checks out a selected component of a package and transmits a copy of the component to a local computer for modification by a user. The user is able to edit and modify the component without having to download the entire package, which is much faster. Once the user completes the editing, the source control management system receives an edited copy of the component from the local computer. Furthermore, the system includes checking in the edited copy and comparing to the unedited component while providing component level warnings of differences. A second copy of the component may be transmitted for independent modification. This allows for multiple users to work on the same component at the same time. The multiple versions of the component are combined and the appropriate modifications are made to the primary component.
